Narrative:

First officer described right brake dragging on rollout. As captain applied brakes below 60 KTS, pedal collapsed to floor -- the left brake that is. Upon releasing and reapplying, left brake worked and taxied normal. However, by the time we reached the gate, #1 brake temperature still read zero while #2 brake was approaching 400 degrees C -- twice the temperature of either right brake. Obviously , #1 did not function on rollout maintenance attempted to bleed the brakes as a solution, and brakes worked good on next flight. Lots of confusion and time trying to bleed brakes. Fancy bleeder would not connect with wheel on, etc, delayed over 1 hour with passenger on board after being told 5-10 mins. If F100 procedures are different, maybe they need to be sent out to maintenance bases.

Title: A FOKKER 100 ON LNDG ROLLOUT CREW DISCOVERED L #1 BRAKE NOT FUNCTIONING PROPERLY. CORRECTED BY BLEEDING #1 BRAKE.

Narrative: FO DESCRIBED R BRAKE DRAGGING ON ROLLOUT. AS CAPT APPLIED BRAKES BELOW 60 KTS, PEDAL COLLAPSED TO FLOOR -- THE L BRAKE THAT IS. UPON RELEASING AND REAPPLYING, L BRAKE WORKED AND TAXIED NORMAL. HOWEVER, BY THE TIME WE REACHED THE GATE, #1 BRAKE TEMP STILL READ ZERO WHILE #2 BRAKE WAS APCHING 400 DEGS C -- TWICE THE TEMP OF EITHER R BRAKE. OBVIOUSLY , #1 DID NOT FUNCTION ON ROLLOUT MAINT ATTEMPTED TO BLEED THE BRAKES AS A SOLUTION, AND BRAKES WORKED GOOD ON NEXT FLT. LOTS OF CONFUSION AND TIME TRYING TO BLEED BRAKES. FANCY BLEEDER WOULD NOT CONNECT WITH WHEEL ON, ETC, DELAYED OVER 1 HR WITH PAX ON BOARD AFTER BEING TOLD 5-10 MINS. IF F100 PROCS ARE DIFFERENT, MAYBE THEY NEED TO BE SENT OUT TO MAINT BASES.
